Abstract
The invention discloses a pesticide composition of herbicide of penoxsulam and oxaziclomefone as well as sulfonylurea, and the mass ratio of the herbicide of penoxsulam and oxaziclomefone as well as sulfonylurea is (1 to 10) to (1 to 30) to (1 to 50), wherein sulfonylurea herbicide is selected from one of metazosulfuron and propyrisulfuron. The pesticide composition is suitable for the control and elimination of rice field weeds; compared with the use of a single dosage or binary combination, the pesticide composition has the obvious advantages of improving the weed control effect, enlarging the weeding spectrum while reducing the amount of pesticide, pollution to the environment is reduced, the generation of herbicide resistance of weeds is delayed, and the service life of the pesticide is prolonged.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, specifically a kind of with penoxsuam, oxaziclomefone and sulfonylurea herbicide for active ingredient composition pesticide, be mainly used in and prevent and kill off paddy field weed.
Background technology
Penoxsuam (penoxsulam): belong to triazolopyrimidine sulfonamide weed killer herbicide, the multiple weeds common to paddy field, comprising barnyard grass, annual nutgrass flatsedge and multiple broadleaved herb all has good preventive effect, and the lasting period reaches 30 ~ 60 days.
Oxaziclomefone (oxaziclomefone): belong in oxazine ketone new herbicides, the mechanism of action is unique, be mainly used in rice field and prevent and treat the multiple weeds such as barnyard grass, waterwort, moleplant seed, difformed galingale herb, medicament is by the root of weeds and cauline leaf basal sink, weeds contact medicament after leaves and stems chlorosis, stop growing, until withered.
Piperazine pyrazosulfuron (metazosulfuron): belong to sulfonylurea herbicide, outstanding to the control efficiency of the weeds such as Monochoria korsakowii, Monochoria vaginalis, mexicana, Procumbent Falsepimpernel, bur beggar-ticks, sweet wine intestines, pondweed, difformed galingale herb, barnyard grass, needle spikesedge herb, Fischer grass.
Promazine Sulfometuron Methyl (propyrisulfuron): belong to pyrimidine radicals sulfonylurea herbicide, is mainly used in paddy field and prevents and kill off the grass family such as barnyard grass and broad leaved weed; This product consumption is low, and the weeds some known sulfonylurea herbicide being produced to resistance have good preventive effect.
Chemical method weeding is agriculturally one of Main Means controlling weeds in field.In recent years, because the large area of some weed killer herbicide kinds is used alone, many weeds have been caused to create pesticide resistance; Meanwhile, because grass when weeds in field occurs is complicated, of a great variety mutually, as the mixing such as grassy weed, sedge weed and broad leaved weed occur, the weed killer herbicide of single variety uses and cannot effectively solve the problem, and all can show defect in a certain respect.
By the screening that different mixture of herbicides is filled a prescription, filter out rational formula, effectively can improve the actual control efficiency to weeds, expand herbicide spectrum, reduce dosage, reduce costs, alleviating the pollution to environment, delay the generation of herbicide resistance, is the important means of the agriculturally weeds comprehensive regulation.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is to provide and is used for preventing and kill off farmland weed by this composition pesticide, is particularly useful for preventing and kill off paddy field weed.
Technical scheme of the present invention: a kind of penoxsuam that contains is with the composition pesticide of oxaziclomefone and sulfonylurea herbicide, and penoxsuam is with the mass ratio of oxaziclomefone and sulfonylurea herbicide is 1 ~ 10:1 ~ 30:1 ~ 50; Sulfonylurea herbicide is selected from the one in piperazine pyrazosulfuron or promazine Sulfometuron Methyl.
Further, penoxsuam is with the preferred mass ratio of oxaziclomefone and sulfonylurea herbicide is 2 ~ 8:7 ~ 25:10 ~ 40; More preferably mass ratio is 2 ~ 8:7 ~ 25:8 ~ 30.
Composition pesticide of the present invention is prepared into any one formulation being applicable to agriculturally using by known method, reasonable formulation is granule, dispersibles oil-suspending agent, suspending agent, microemulsion, wetting powder, water dispersible granules, effervescent tablet and aqueous emulsion.
The auxiliary agent used in composition pesticide of the present invention comprise solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other to be of value to active ingredient stable and play the known substance of drug effect in the formulation, all various compositions that are conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of composition pesticide of the present invention and amount of application change with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Composition pesticide of the present invention is applicable to prevent and kill off paddy field weed.
Compared with prior art, the invention has the advantages that:
1, penoxsuam, oxaziclomefone and sulfonylurea herbicide ternary built have significant synergistic function, the control efficiency significantly improved weeds is used than single dose or binary built, expand herbicide spectrum, a dispenser can solve the weeds such as paddy field grassy weed, sedge weed and broad leaved weed simultaneously.
2, penoxsuam, oxaziclomefone and sulfonylurea herbicide ternary built, decrease Pesticide use amount, reduces use cost, alleviates pollution to environment, delayed the generation of herbicide resistance, extends the service life of agricultural chemicals.
